worst type of thyroid cancer
anaplastic
thyroid cancer that spreads via blood
follicular
thyroid cancer associated with MEN
medullary
medullary cancers originate from what cells
parafolicular C cells
what do medullary/c cell cancers release
calcitonin
what does calcitonin do
reduces blood calcium
which 2 thyroid cancers have same cellular structure so hard to differentiate via FNA
follicular adenoma and carcinoma
which cancer occurs in iodine rich areas
papillary
which cells and hormone lead to increased blood Ca+
parathyroid releases PTH = inc blood calcium
stimulation of adrenal medulla to release adrenalin
pre-ganglionic sympathetic fibres
cells of parathyroid
chief cells
chief cells release
parathyroid hormone
c cells found where
follicle of thyroid
what can cause direct aldosterone release from adrenal cortex
high K+ blood
high Na+ and high glucose
cushings
what is low in addisons
cortisol
addison bloods will show
low glucose
low sodium
high potassium
hypotension
cells that release epinephrin
chromaffin
release of glucocorticoids into blood results in what
proteins and fats converted to glucose
glucose goes up
immune system supressed
what effect does aldosterone have
retention of sodium and water
incr BP
glucagon produced by what cells
alpha in pancreas
glucagon does what
trigger gluconeogenesis and glucogenolysis = increase in blood glucose (opposite role of insulin)
most common thyroid cancer
papillary
papillary spreads how
lymph (can present with goitre and lymphadonopathy)
